exposed edges of the shingles and prevent the edges turning upwardly because of warping or bending by winds or otherwise. Another object is to provide shingles so formed single thickness lapping only sufliciently to prevent leakage and at the same time forming a dependable and waterproof roof covering.

In the formation of the shingles which embody the features of my invention .1 have provided a. shingle which has substantially no. surplus material and which can be cut from standard strips without any waste portions being cut from the strips and a further object is to provide a suitable method for cutting out shingles from strips of shingle material. A further object is to provide shingles so formed that they can be assembled on the roof conveniently and expedicertain portions of the shingles forming guides for laying the shingles. objects of the invention will be apparent from the accompanying drawings and. the following description thereof: I Of the drawings Fig.1 is a strip; Fig. 2-is a plan view of the assembled shingles on a roof; Fig. 3 is a plan view of an enlarged unit shingle showing the details thereof; and 4 is a plan view of a modified form of shingle. I v y The individual shingles are in eneral shaped like a parallelogram and pre-erably a square, but at one. corner of the shingles I form-lugs 11 and 12. When'laid on the roof these lugs. are on the lower-1 corner of the-shingle and are adaptedto: lie under the respective adjacent under-lying shingles 13 and 14. In this manner the under-lying shingles hold down the exposed corners of In order to produce this result I provide in the lower edges 15 and 16 of eachjshingle'slits' or slots 17 and 18 and-in laying the shingles the shoulders 19 and 20 of the lugs 11 and 12 are p..ssed into the slits, as indicated, thus providing a complete locking means for the exposed portions Other v plan view of a strip of shingle material indicating howthe individual shingles are cut from the-- cutting pairs of main' slits, slits and 26 and slits 27 and 28 form-- of the shingles and improving the appear-' ance of the design, and otherwise adding to the value of the invention. The slit assists n preventing the lugs from being forced out from under .the other shin le. This slit also provides very effective guide means for laying the shingles, as it s necessary only to slip the shoulders 19 and 20 into the respective slit-s and force the upper shingle upwardly as far as it will go and it is then in its correct position. As indicated in Fig. 2, the length of these slits is equal to the perpendicular distance from the outer edge of the lug 11 or 12 to the point of connection of the lugto the side of the shingle.

' But as\a further guide means, and one which is sufficient itself if it is desired, is the recess 21 formed in one of the corners of the shingle which is adapted to receive thecorner 22 or the adjacent shingle. In laying the shingles, the shingle 23 has its corner 22 slipped intothe recess 21 of the shingle 24. Preferably the edges of the recess 21 are homologous in shape with the edges ofsthe corner 22, and when these two sets of edges coincide the shingle is inits proper place. formed by the shoulders 19 and 20 and slits 17 and 18, together with the registering of the'recesses 21 and corners 22, the shingles may be very exactly laid.

'M'y method of cutting out shingles of this general shape is indicatedby Fig. 1- in which a'strip of shingle material is out into two rows of shingles, and the method consists in forming one pair ing another pa1r, and in cutting these slits along converging lines to. points adjacent to the point 29 where the lines would cross it But by the use of the guides continued; then in cutting slits 30 and 31 connecting the respective pairs of main slits,

and finally in cutting slit '32 which connects the connecting slits 30 and 31. In this manner the lugs 11 and 12 are formed and they are of such shape as to form of proper shape the recess 21. In this instance the pairs of main slits are at right angles to each other, but obviousl other angles might be used.

Figure tshows a modified form of shingle which has a projecting lug 35 and a corresponding recess 36, the lug of one shingle being formedsby the material taken from the adjacent shingle to form the recess 36. The edge 37 of the lug is adapted to coincide with the edge 38 of the over-lying ad a- "cent shingle. By this arrangement with the edges 37 and 38- registering a double thickness of the exposed edge isformed which adds to the appearance of the shingles when parallel and its adjacent edges perpendicular to each other, and lugs extending outwardly from two adjacent sides at one corner of the shingle; another corner of the shingle having a recess formed therein.

2. A shingle having its opposite edges parallel and lugs extending outwardly from onecorner of the shingle, another corner of the shingle having a recess formed therein.

3. A shingle having its opposite edges parallel and lugs extending outwardly from one corner of the shingle, another corner of the shingle having a recess formed therein; and slits projecting inwardly from the edges which are adjacent the said lugs.

4. A shingle having its edges forming substantially a parallelogram but with lugs projecting from one corner, said lugs forming substantially a rectangular parallelogram in combination with a trapezoid; and slits projecting inwardly from the edges of the shingle which are adjacent said corner.

5. A shingle having the general shape of a square but with lugs pro ecting from one corner; said shingle having a recess formed in another corner, the edges of the recess be ing substantially homologous with the edges of the corner. opposlte the corner in which the recess is formed' 6. A plurality of shingles laid in rows on a roof, the general contour of each shingle forming a square, and each shingle having a recess in one of its corners into which the corner of an adjacent shingle projects, and a lug extending fromthe lower portion of each shingle and projecting under the adjacent under-lying shingle. v

7. A shingle having two adjacent edges at right angles to each other and a lug extending from the converging ends of the edges, the outer edge of the lug straight and at an oblique anglewith each of the said adjacent edges; and saidshingle having a slit projecting inwardly from each of said adjacent edges; and a second lug projecting from one of said adjacent edges,-

one edge of said second lug being parallel being aeeae's'awith the'said outer edge of the first mentioned lug.

8. A shingleihaving two straight converging adjacent edges anda lug extending from the converging ends of the edges, the outer edge of the lug beingstraight and at an oblique angl'ewith each of said edges, and a second lug projecting'froln one of said adjacent edges, one edgei'of said second lug being parallel with said outer edge of said first mentioned lug.

9. A shingle having two adjacent edges at right angles to each other and a lug extending from the converging ends of the edges, the outer edge of the lug being straight and at an oblique angle with each of the said adjacent edges; and said.'.shingle having a slit projecting inwardly from each of said adjacent edges; and a second lugprojecting from one of said adjacent edges, one edge of said second lug being parallel with the said outer edge of the first mentioned lug, said oblique angles being equal. 10. A shingle having, twoadjacent edges at right angles to each other and a lug extending from the convergin ends of the edges, the outer edge of the .lug being straight and at an oblique angle with each of the said ,adjacent edges; and said shingle having a slit projecting; inwardly from each of said adjacent edges ;'and a second lug pro jecting fromone of'said adjacent edges; one edge of said second 111 being parallel with the said outer edge 0 the first mentioned lug, the length of the slit bein equal to the perpendicular distance from the outer edge of the first mentioned lug to the connection of the lug with one of said sides.

11. A shingle having two adjacent edges at right angles 'toeach other and a in tending from the "converging ends 0? the edges, the outer edge of the lug bein straight and at an oblique angle with eac of the said adjacent'edges; and said shingle having a slit projecting inwardly from each of said adjacent edges; and a second lug projecting from one of-said adjacent edges, one edge of said-second lug with the said outer edge of the first mentioned lug, said slit commencing at the inner end of said edge-of said second lug.
